HENRY H. PHILLIPS, OF JUDITH GAE, MONTANA LANDING GEAR FOR AEROELAJETES Application filed August 9, 1928. Serial No. 298,510.

The present invention relates'generally to aeroplanes and more particularly to a resilient landing gear therefor and has for its prime object to provide means for breaking the speed of the aeroplane when the same has landed.

Another very im vention resides in ri 'tant object of the In- *ovision of a landing into action and provides yielding res .co to landing shocks that might otherwise damage or destroy the aeroplane. v

A still further very important object oi the invention resides in the provision of an extremely simple rear landing gear which may be steered for maneuvering on the' ground.

A. further important object of the inventlon resides in the provision of a landing gear of this nature which is'strong and durable, inexpensive to manufacture and i nstall, thoroughly efficient and reliable in use and operation, and otherwise Well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a side elevation of an aeroplane embod the features of my invention;

Figure is a fragmentary bottom lan View thereof showing my improved lan ing gear, and

Figure 3 is a vertical transverse section taken substantially on the line 33 of Figure 1 looking in the direction of the arrows.

Referring to the drawing in detail it will be seen that the numeral 5 denotes the fuselage having the wing 6 and front running gear 7.

These parts are of conventional construction and have been illustrated merely for the purpose of bringing out the utility of my improvement.

My improvement refers particularly to the rear landing gear and includes a semi-cylindricalspring 8 anchored by suitable means 1) intermediate its ends to the bottom of the since in actual prac fuselage 5 adjacent the rear end thereof. This spring extends transversely and is pivotaliy engaged with spring perches 9 on an angle ll upon the ends of which are journaled Wheels 12 having brakes 14 associated therewith.

These wheels are mounted on the axle so as to be dirigible but suitable knuckles 15 are connected together by tie rods 16 so as to move in unison.

ihe wheels are actuated for steer J purposes through a rod 1'? which is en gageu' with a-pivoted foot bar 18 in the cockpit of ii fuselage 5. The brakes are actuated througn rods 19 actuated by a lever 20 in the cockpit.

Shock absorbers associated with the rear landing gear a includes springs 22 anchored by suitable means on the sides of the fascia d connected with the end portions .1 tie ll by means adjustable straps 24.

The landing gear may have any suitable nuznbei of heels and brakes may be associated over the Wheels.

From the above detailed dcscr ion it will be seen that the ac: plane may be efiicicntly maneuvered a illt mud in a reliable manner and when :ing a landing shock of the landing will be absorbed to a great extent by the spring 8 a; d the rebound prevented from being excessive by the shock absorber described. Furthermore the brakes are efficient in b akin the aeroplane to a stop Within comparatively short distance after the same has landed on the ground thus eliminat;

quires considerable room for the ordinary aeroplane to land in.

It is thought that the construction, operation, utility and advantages of the invention will now be quite apparent to those skilled in this art Without a more detailed descrip tion thereof.

The present embodiment of the invention has been described in considerable detail merely ior jllfi pur oses of exemplification tree it will attain the features of advantage enumerated asdesirable in the statenu-nt of the invention and the above description.

I claim as new is:

It will be apparent that changes in the details of construction, and'in the combination and arrangement of parts may be resorted to without departing fromthe spirit or scope of the invention as hereinafter claimed or sacrificing an of its advantages.

Having thus escribed my invention what In an aeroplane including a fuselage, a rear landing ear therefor including a transversely exten "ng semi-elliptical spring, means for securing the center of the spring to the fuselage, the ends of the spring terminatin below and within the plane of the sides 0 the fuselage, a dead axle having its ends extending beyond the sides of the fuselage, means for securing the ends of the spring to the dead axle, and dirigible Wheels carried by the ends of the axle and disposed beyond the sides of the fuselage.

In testimony whereof I aflix my signature.

HENRY H. PHILLIPS;
